一、砌筑水泥的生产及性能砌筑水泥是种用来代替常规水泥配制砌筑砂浆,抹面砂等的低标号水泥。西方一些发达国家研究应用较早,如美国和西德在五十年代就进行了较系统的研究,并制定了国家标准和不同用途的具体规范。我国是七十年代末八十年代初开始对砌筑水泥进行研究的。国家于1983年5月1日发布了砌筑水泥的国家标准(GB3183-82)。在我国较早研究砌筑水泥的单位有国家建材研究院水泥研究所,湖南省建材研究设计院等单位。国家建材研究院水泥研究所利用煤矸石、粉煤灰为主要原料,掺入部分水泥熟料和石膏等研制的砌筑水泥在山东烟台市水泥厂及江苏常州市第二水泥厂进行过小批量试生产并获得成功,一九八二年六月通过了国家鉴定。湖南省建材研究设计院等单位以石煤沸腾炉灰渣作主要原料,在其中
First, the production and performance of masonry cement Masonry cement is a kind of low-grade cement that is used to replace conventional cement to prepare masonry mortar, plaster sand and so on. Some western developed countries have applied research earlier. For example, the United States and West Germany carried out more systematic research in the 1950s and formulated specific standards for national standards and different uses. China began to study masonry cement in the late 1970s and early 1980s. The state issued the national standard for masonry cement (GB3183-82) on May 1, 1983. Earlier research units for masonry cement in China include National Institute of Building Materials Research Institute of Cement, Hunan Provincial Building Material Research and Design Institute and other units. The Cement Research Institute of the National Building Materials Research Institute used coal gangue and fly ash as the main raw materials, and the masonry cement that was developed by incorporation of some cement clinker and gypsum had undergone small batch production at the cement plants in Yantai, Shandong and the second cement plant in Changzhou, Jiangsu. Pilot production and success, passed the national appraisal in June 1982. Hunan Provincial Building Material Research and Design Institute and other units use stone coal boiling ash as the main raw material, in which
